CLAMPING MEANS FOR FOOT-SUPPORTS.

Application filed June 5, 1915.

To all whom it may concern: 7

Be it known that 1, JOHN G. UNnnRwooD, a citizen of the United States of Amerlca, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements 1n Clamping Means for Foot-Supports, of whichthe following is a specification.

This invention relates to a means for clamping shoes or the like to a foot support which. is preferably mounted upon a pedestal.

It is well known that in the operation of polishing and shining shoes, as practlsed by the attendant of and at a conventional type of shoe shining stand, that the patrons foot rests upon a foot support which is mounted upon a pedestal and that the act of polishing or shining the shoes of the-patron has a tendency to shift or move the foot laterally and endwise of the foot support, thereby making it difficult and inconvenient for the attendant to perform the work satlsfactorily and with expediency and that a burden is also imposed upon the patron 111 making an effort to hold the foot stationary upon the foot support.

The primary object of this invention therefore is to provide means of securely retaining the foot of the patron upon the foot support and preventing all movement thereof without the exercise of any physical or mental eifort upon the part of the attendant or patron.

A. further object is to provide simple and efficient means of interchanging the conventional type of foot support and pedestalfor the type shown in the present lnvention, having the clamping means applied thereto.

The preferable specific construction employed comprises an adjustable clamping means in combination with means for l0cking the same in frictional contact with the sole of the shoe of the patron, and means for automatically returning the clamping means to open or free position when the clamping means is released from the locking means.

I attain these and other objects by the mechanism illustrated in the accompanying drawing in which Figure 1 is a fragmentary bottom view of the foot support showing the clamping member of the clamping means in a partially open position. Fig. 2 is a side elevation of the invention, showing the foot support mounted upon a pedestal and the clamping Specification of Letters Patent.

Serial No. 32,253.

In the drawings, reference numeral 1 illustrates a base and 2 a pedestal upon which a foot support 3 is mounted, preferably at an incline with the base. A disk 1 is rotatably mounted upon a screw 5 and spaced apart from the bottom of the foot support by a washer 6. Pins or screws 7 and 8 are secured to the disk in spaced relation from the axis of the bolt 5 and in substantial alinement with each other.

Clamping members 9 and 10 are pivot-ally secured to the disk 1 by the pins 7 and 8 and their ends 11 and 12 are upturned extending above the top of the foot support. They are arranged in substantial alinement with each other. The clanniiing' members 9 and 10 are provided with slots 13 and 14: which are engaged by the guide pins or screws 15 and 16. A yielding spring operating lever 17 is pivotally secured to the pedestal to swing vertically. A lip 18 is formed on the lever 17 and is yieldingly and movably pressed in contact by its own tension with the ratchet teeth 19 of a yoke shape bar 20 which is secured to the pedestal by a bolt 2l'thereby effectively locking the lever 17 against movement. At a pre-deten mined point on the disk 4, a pin or screw 22 is secured and a link 23 is connected to the screw 22 and to the top portion 2 1 of the lever 17.

The operation of the invention is as follows: The operator grasps the lower portion 25 of the lever 17 and pulls outward counteracting its tension and withdrawing the lip 18 from its contact with the teeth 19 and then swings the lever forward which imparts a rotary movement to the disk which in turn slidably forces the ends 11 and 12 in contact with the sole 26 of the shoe of the patron thereby securely clamping it to the foot support. When the end 25 of the lever 17 is released, it automatically forces the lip 18 in contact with the alined tooth that coincides with the adjustment of the clamping members to the sole of the shoe of the patron, thereby locking the lever.

In order to prevent the lever from swing ing too far forward when it is being swung to release the clamping members from the sole of the shoe of the provided.

To automatically return the clamping members to their open or free position, a coil spring 28 is provided which eXerts its patron, a stop 27 is tension to swing the lever 17 rearwardly.

For convenience of the attendant, a hook 29 is provided to aiiord facilities for hang- The clamping members are connected in diametrically opposed relation to the disk, and the pinsupports for the clamping members are in alinement with the connections 7 and 8 when said clamping members are at their maximum of open position. As a result-of this structure it will be apparent that as the clamping members are moved toward clamping position, their relatively inner ends are moved circumferentially so that increased lengths of the clamping members are moved between the disk and foot 7 support as said members are brought into clamping relation. This provides for a rigid support of the clamping members and insures their efliciency notwithstanding the fact that the parts may be comparatively light.

WVhat is claimed is:

l. The combination with a shoe support, of a disk mounted for rotary movement on and in spaced relation to the under surface of said support, clamping members pivotally connected. to the disk at diametrically opposite points and disposed intermediate Copies '01 this patent maybe obtained for fivecents each, by addressing the Commissioner of Patents.

' otally connected to the disk at diametrically opposite points and disposed intermediate the disk and shoe support, a lever pivotally mounted with relation to the support,means connecting the lever and disk, and a spring for operating the lever in one. direction.

3. The comblnation with a shoe support, of a disk mounted for rotary movement on and in spaced relation to the under surface of said support, clamping members pivotally connected to the disk at diametrically opposite points and disposed intermediate the disk and shoe support, guiding means for themembers arranged in alinement transversely of the support, and means for operating the disk to dispose the disconnected ends of the members on opposite sides of the; line joining the guiding means for the members, whereby the members in clamping relation are arranged in a parallel plane at an angle to the transverse line of the support.

In testimony whereof I afliX my signature in presence of two witnesses.
